실험 절차

Acetyl chloride (1.05 equivalent) in methylene chloride (50 mL) was added dropwise to a solution of 3-(2,5-difluorophenyl)imidazolidine-2,4-dione (50 mmol) in methylene chloride (150 mL) containing triethylamine (1.1 equivalent) and a catalytic amount of dimethylaminopyridine. The solution was allowed to stir overnight at room temperature, then was diluted with methylene chloride, and washed with 10% HCl, with water and with brine (saturated), dried (MgSO4), filtered and concentrated to give N-acetyl-3-(2,5-difluorophenyl)imidazolidine-2,4-dione.
